1
These capacities are gross ratings. For net capacity, determine the KW of the supply air blower motor from the Blower Performance Table, multiply this value by
3.415 MBH / KW to determine the motor heat, and deduct this heat from the gross capacity of the unit.
2
These ratings include the compressor and the outdoor fan motors but not the supply air blower motor. The total outdoor fan motor power input is 0.35 KW.
Refer to the Blower Performance Table for the KW of the supply air blower motor.
